You are welcome. You might consider bulk charcoal instead of the clay. Although the clays draw very well, they will pull out minerals as well, so you might want to monitor and supplement the minerals. Charcoal does not (in my experience) pull minerals and is wonderful with a fiber mix. I use psyllium with bulk oat bran and whole flax seeds.
Dr. Klingheardt (sp) recommends using a bulk fiber to help draw out the toxins.
On the glutathione issue, glutathione is troublesome to get into the blood stream as you know. I am not sure of the sublingual but I and others have had good success with Readisorb. It is protected by a liposomal delivery system.
